What would the world be like if the British had lost to Napoleon in the battle of Waterloo, or if the Japanese had won World War II? In The Difference Engine, authors William Gibson and Bruce Sterling ask a similar question: What would have happened if nineteenth-century inventor Charles Babbage had succeeded in creating the world’s first automatic computer? (Babbage had the right idea, but the technology of his time wasn’t up to the task.) Here is Gibson and Sterling’s answer: with the aid of powerful computers, Britain becomes the world’s first technological superpower. Its first foreign adventure is to intervene in the American Civil War on the side of the U.S. South, which splits the United States into four feuding republics.
